METHOD OF TREATING USED BURLAP BAGS Filed Sept 5, 1929 ,MHH [UltimPatented May 1.3, 1930 UNITED STATES PATENTv OFFICE GEORGE I. GOLDWYN,OF CHICAGO, ILLINOIS, ASSIGNOB OF ONE-HALF TO HERMAN GOLDWYN, 0FCHICAGO, ILLINOIS :METHOD 0F TREATING l'USED BURIiAP BAGS Applicationfiled September 5, 1929. Serial No. 390,493.

This invention relates A:to an -improved method ofv treating usedbnrlapbags and it consists of the mattersherinafter described and moreparticularly pointed out in the ap- 5 pended claims.

The primary object'of the invention is to provide a method whereby` usedburlap bags may be treated to lit them for further c'om-V mercialuse.

Another object of the invention is to so treat a used burlap bag thatits usual1yeX- posed edges are secured against ravellingor fraying.

Theseobjects of the invention'as well as with my speciiication.

In the drawings Fig. l is a perspective view of a used bur. lap bagafter having been'treated in accordance vwith my improved method.

Fig. 2 is a transverse sectional view through the seam of a new burlapbag before thebag is turned with the outside out. g i Fig. 3 is atransverse sectional view through the seam of Fig. 2 after the rbag hasbeen turned to bring the outside out. F ig. 4 is va perspectivesectional view through the seam of a usedbag after having been treatedinaccordance with 'my improved method.

With the demand established inthe business world for goed, strong, lowcost burlap bags,- many in ustries have been` built up around thetreating of used burlap bags to restore them to a condition adaptingthem for re-use. Such bags are cleaned and the seam rips and fabricholes are stitched or sewn so as to effectively hold the commoditieswith which they are illed in re-use. A

Certain established laws prohibit the rcuse ofv such-bags with theoriginal brand or trade-mark relating to the original contents exposedto View, so that it has been the pracbrand or trade-mark is in effectobliterated'.

Such a practice also permits a better cleaningothers together with themany advantages thereof will more fully -appear as l proceed tice .tovturn the bags inside out, whereby said- .beyond the associatedstitching.

The fabric from which burlap bags are IliadeY is comparatively loosewoven and is usually made vfrom jute fibers. Such fabricquicklyravels'and frays at its cut edges and forms lint which sloughsolf so ythat it tends to disintegrate. l

Invforming a burlap bag, a piece of fabric of twice the area of afinished bag is cut from a bolt of such' burlap fabric usually salvagedalong both margins and this piece is folded upon itself .to form theopposite side walls 1 and 2 respectively ofthe bag to be made `as. bestshown in Fig. l.

In stitching the cut fabric into bag form, a margin la and 2arespectively of each wall of the bag is turned vback upon the bag fabricand a line of stitching 3 is then runv along' one side and one end ofthe folded bag fabric' to form one of the closed sides and the bottom ofthe' bag. Thus the stitching passes-through four thicknesses of fabricas shown The stitched and folded bag blank is then turned to bringl theoutside 'out as shown in Fig. 3 and this bringsthe margins 1' and 2 onthe inside 'of the bag. The bag then will be ready for filling, and itsopen top is closed in any desired manner.

After the original contents have been emptied from the bag, theempty bagwhich has heretofore been considered as an economie Waste, is now savedand is turned inside out and is thoroughly cleaned and repaired' whereneeded and then it takes its place'for sale as a reconditioned used bag.

In reconditioning the bag it'is re-turned inside out and is generallysuction cleaned 'and this removes all content and dust particles fromthe bag and removes alllint from the seams A W'ith the bag lie-turnedinside out such brands and trade-marks which origi- .nally appeared onthe outside of thba are in Fig. 2.

tively of said margins, outwardly beyond the line of stitching 3are-usually ravelled and present a frayed appearance to the bag. Thisfrayed or ragged appearance detracts from resale value: of the bag whensold for re-use in this condition and such frayed edges will eventuallyslough off as lint, up to said line of stitching which could easily pullthrough the f abric u nder bag load with the result that the bag wouldopen up at points alongsaid line of stitching.

To overcome the objections noted lI fold over said edge portions 1b and2b respectively, back upon said margins to cover up said line ofstitching 3 and then gather in the frayed ends of the warps and weftsthereof and secure said parts together in any suitable manner. I findone convenientmanner of doing this is to run the` stitched margins ofthe bag through a sewing machine equipped with suitable folders to foldover said frayed ends of the warps and'weftsand then stitch the bagparts together by an overcast stitch 4 asbest shown in Fig. 4.- Thisovercast stitch passes through the bag fabric along a line 4 spacedinwardly from thefolded over margins and the loops 4b of said overcaststitch pass about said folded over margins and binds or secures saidfrayed ends in place.

Thus an overcast seam is provided for the bag, which reinforces theoriginal line `of stitching 3 and the frayed ends of the marn ginalvparts lb and 2 respectively, are gathered'in and bound in place so thata good strong and neat seam is provided for the bag which greatlyenchances its resale value..

By my improved method, I am enabled tov put a used burlap bag in abettercondition for re-use and I am enabled Lto restore such bags as haveheretofore been discarded as waste into a condition suiting them forfuru ther re-use, then has been possible in methods heretofore employed.

While in describing ,my improved method, I have referred in detail tothe various steps, and to the sequence thereof, the same is to beconsidered' merely as illustrative so that I do not Wish to be limitedthereto except as may be specifically set forth .in the appended claims.Y

I claim as my invention 1. The method of treating used burlap or likebags which consists in providing a bag turned inside out to expose thefolded over margins of the bag fabric and the frayed edges thereof aswell as the line of stitching v securing said folded over marginstogether,

in folding over the frayedl edges of the margins back upon said line ofstitching to cover the same and then securing said frayed edges to theunfrayed parts of said mar 'ns.

2. The method of treating used urlap or like bags which consists inproviding a bag turned inside out to expose the folded over margins ofthe bag fabric and the frayed edges thereof as well as the line ofstitching securing said folded over margins together, in folding overthe frayed edges of the margins back upon said line of stitching tocover thesame and providing a second line of stitching adjacentsaidmargins to secure said frayed edges to the unfrayed parts of saidmargins. y

3. The method of treatingvused burlap or like bags which consists inproviding a bag turned inside out to expose the folded over margins ofthe bag fabric and the frayed edges thereof as well as the line ofstitching securing said folded over margins together, in folding overthe frayed edges of the margins back upon said line of stitching tocover the same stitching the bag fabric together adjacent said marginswith an over cast stitch which binds the frayed edges to the unfrayedparts of said margins.

In testimony whereof, I have hereunto set my hand this 29th da of Au st,1929.
